This application relates to the field of communication technologies, and discloses a method and an apparatus for determining a link for forwarding a service flow, and a storage medium. A first forwarding device obtains identification information of a first service flow; and determines, based on the identification information of the first service flow, a link bandwidth matrix, and link statuses respectively corresponding to N links, a first link for forwarding the first service flow. A hash operation does not need to be performed based on a device identifier of each forwarding device, and a specific forwarding device that performs forwarding does not need to be determined by comparing a plurality of hash values.
